I have some old ACM CALGO fiches here (4x5") about 25x15 pages per and, out
of curiosity, scanned them on a Canoscan with film capabilities at 1200 and
then 2400 dpi.
Nothing recognizable other than title pages. But then, a little
back-of-the envelope math tells me to expect that. Given 25 pages across
the 5" width, a single page occupies less than 0.20 inches. Even at 2400
dpi, that's only 120 dots per page (actually, given the blank space around
the page, it's probably closer to 80.
Cheers,
Chuck
